This paper chronicles the preparation, describes the course content, and details the evaluation of a course designed to train police officers in interpersonal communication. Training was done in two-hour sessions for a police department that was implementing the philosophies and activities of community policing. The paper discusses the needs assessment, which also served to get trainees to begin thinking about the subject of the training. It categorizes the responses from the needs assessment in five areas: communication, attitude, emotion, beliefs, and situational. Teaching the course helped to clarify for the instructor what it means to participate in applied communication study in a "real" world setting and that each trainer would take different lessons from the experience.
